As shown in fig. 1, a schematic structural diagram of an LED lamp panel with redundant display in an embodiment of the present invention is shown. The LED lamp panel 100 of this embodiment includes: the device comprises a main decoding module 101, a standby decoding module 102, a statistic arbitration module 103, a data selection module 104, a data output module 105, a main driving module 106, a standby driving module 107, a main LED lamp bead module 108 and a standby LED lamp bead module 109.

The main decoding module 101 and the standby decoding module 102 are connected to the statistical arbitration module 103; the statistical arbitration module 103 is connected with the data selection module 104; the data selection module 104 is respectively connected with the main decoding module 101, the standby decoding module 102, the statistic arbitration module 103 and the data output module 105; the data output module 105 is connected with the main drive module 106 and the standby drive module 107; the main driving module 106 is connected with a main LED lamp bead module 108; and the standby driving module 107 is connected with a standby LED lamp bead module 109. Hereinafter, each module of the LED lamp panel will be explained in detail.

The main decoding module 101 receives a main signal, and the standby decoding module 102 receives a standby signal, and is configured to perform decoding processing on the received signal. Each decoding module comprises but is not limited to a serial data, parallel data and differential data decoding module;

the arbitration module 103 is connected to the main decoding module 101 and the standby decoding module 102, and is configured to perform main/standby arbitration. It should be understood that the main/standby arbitration means that the arbitration module 103 arbitrates the control right between the main decoding module 101 and the standby decoding module 102 according to the bit error rate and the display synchronization information, that is, arbitrates whether the information decoded by the main decoding module 101 or the information decoded by the standby decoding module 102 is currently to be processed. Further, the arbitration module 103 may be further configured to count information of the decoded main signal and/or standby signal.

And a main driving circuit and a standby driving circuit which are mutually backed up are arranged in the LED driving stage, so that the redundant backup in the driving stage is realized. In addition, the LED lamp bead module is also provided with a main LED lamp bead and a standby LED lamp bead which are mutually backup, and finally the redundancy backup of the LED lamp bead level is achieved.

The utility model comprises the LED lamp panel with the redundant display.
